Miniature rose variety &#39;POULty002&#39;

ABSTRACT

A new miniature rose plant which has abundant, golden-yellow flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

[0001] The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing betweenan unnamed seedling, and ‘POULjol’ both unpatented varieties. The twoparents were crossed and the resulting seeds were planted in acontrolled environment. The new variety is named ‘POULty002’.

[0002] The new rose may be distinguished from its seed parent, anunnamed seedling, by the following combination of characteristics:

[0003] 1. The seed parent has orange-red blooms, whereas ‘POULty002’ hasgolden-yellow blooms.

[0004] 2. The seed parent, as a miniature rose, is taller in growth than‘POULty002’.

[0005] The new variety may be distinguished from its pollen parent,‘POULjol’ created by the same inventors, by the following combination ofcharacteristics:

[0006] 1. The pollen parent has clear yellow blooms, whereas ‘POULty002’has golden-yellow blooms.

[0007] 2. ‘POULjol’ has a larger, bushier habit than ‘POULty002’.

[0008] The objective of the hybridization of this rose variety forcommercial culture was to create a new and distinct variety with uniquequalities, such as:

[0009] 1. Uniform and abundant golden-yellow flowers;

[0010] 2. Vigorous and compact growth;

[0011] 3. Year-round flowering under glasshouse conditions;

[0012] 4. Suitability for production from softwood cuttings in pots;

[0013] 5. Durable flowers and foliage which make a variety suitable fordistribution in the floral industry.

[0014] This combination of qualities is not present in previouslyavailable commercial cultivars of this type and distinguish ‘POULty002’from all other varieties of which we are aware.

[0015] As part of their rose development program, L. Pernille Olesen andMogens N. Olesen germinated the seeds from the aforementionedhybridization and conducted evaluations on the resulting seedlings in acontrolled environment in Fredensborg, Denmark.

[0016] ‘POULty002’ was selected by the inventors as a single plant fromthe progeny of the hybridization in spring 1997.

[0017] Asexual reproduction of ‘POULty002’ by cuttings and traditionalbudding was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in June 1997. This initial and othersubsequent propagations conducted in controlled environments havedemonstrated that the characteristics of ‘POULty002’ are true to typeand are transmitted from one generation to the next.

[0018] The accompanying color illustration shows as true as isreasonably possible to obtain in color photographs of this type, thetypical characteristics of the buds, flowers, leaves, and stems of‘POULty002’. Specifically illustrated in SHEET 1:

[0019]1. Stem showing branching and the attachment of leaves, buds, andpeduncles;

[0020] 2. Flower bud, partially opened bud, and open bloom;

[0021] 3. Flower petals, detached;

[0022] 4. Sepals, receptacle, and pedicel;

[0023] 5. Stem as well as a bare stem exhibiting thorns;

[0024] 6. Leaves.

DETAILED DESCRIPTION OF THE VARIETY

[0025] The following is a description of ‘POULty002’, as observed in itsgrowth in glasshouses in Fredensborg, Denmark; and Half Moon Bay,California. Color references are made using The Royal HorticulturalSociety (London, England) Colour Chart, 1995, except where common termsof color are used.

[0026] For a comparison, several physical characteristics of the rosevariety ‘POULgildo’, a rose variety from the same inventors describedand illustrated in U.S. Plant patent application Ser. No. 09/677,573,dated Sep. 27, 2000 are compared to ‘POULty002’ in Chart 1.
